The task requires the script to delete the ShopDB database if it already exists. To meet this requirement and make the script re-runnable, you should add the DROP DATABASE IF EXISTS ShopDB; statement before creating the database.


USE ShopDB;

CREATE TABLE Countries (
ID INT,
Name VARCHAR(50),
PRIMARY KEY (ID)
);

CREATE TABLE ProductInventory (
ID INT,
ProductName VARCHAR(50),
WarehouseAmount INT,
CREATE TABLE Products(
ProductId INT AUTO_INCREMENT PRIMARY KEY,
Name VARCHAR(50)
);



CREATE TABLE Warehouse(
WarehouseID INT AUTO_INCREMENT PRIMARY KEY,
WarehouseName VARCHAR(50),
WarehouseAddress VARCHAR(50),
CountryID INT,
FOREIGN KEY (CountryID) REFERENCES Countries(ID) ON DELETE NO ACTION,
PRIMARY KEY (ID)
FOREIGN KEY (CountryID) REFERENCES Countries(ID)
);

-- Populate test data

INSERT INTO Countries (ID,Name)
VALUES (1, 'Country1');
INSERT INTO Countries (ID,Name)
VALUES (2, 'Country2');

INSERT INTO ProductInventory (ID,ProductName,WarehouseAmount,WarehouseName,WarehouseAddress,CountryID)
VALUES (1, 'AwersomeProduct', 2, 'Warehouse-1', 'City-1, Street-1',1);
INSERT INTO ProductInventory (ID,ProductName,WarehouseAmount,WarehouseName,WarehouseAddress,CountryID)
VALUES (2, 'AwersomeProduct', 5, 'Warehouse-2', 'City-2, Street-2',2);



CREATE TABLE ProductInventory(
ProductID INT NOT NULL ,
ProductAmount INT NOT NULL,
Warehouse_ID INT NOT NULL,
FOREIGN KEY (ProductID) REFERENCES Products(ProductID),
FOREIGN KEY (Warehouse_ID) REFERENCES Warehouse(WarehouseID),
PRIMARY KEY (ProductID, Warehouse_ID)
);

INSERT INTO Countries(ID, Name)
VALUES(1, "Country1");

INSERT INTO Countries(ID, Name)
VALUES(2,"Country2");

INSERT INTO Products(Name)
VALUES ("AwersomeProduct");

INSERT INTO Warehouse(WarehouseName, WarehouseAddress, CountryID)
VALUES("Warehouse-1","City-1, Street-1",1);
INSERT INTO Warehouse(WarehouseName, WarehouseAddress, CountryID)
VALUES("Warehouse-2", "City-2, Street-2",2);


INSERT INTO ProductInventory(ProductID, ProductAmount,Warehouse_ID)
VALUES (1, 2, 1);
INSERT INTO ProductInventory(ProductID,ProductAmount,Warehouse_ID)
VALUES(1, 5, 2);
